CULPEPER, Va. (WUSA9) -- Three children and two adults were found dead by a family member Sunday night after a murder-suicide, according to the Culpeper County Sheriff's Office.

Police say 35-year-old Clarence Washington shot his wife Shauna, and then shot their three daughters, ages four, six and 13, at their home in the 4400 block of Rixeyville Road in a rural area of Culpeper County. WNEW reports the daughters were 13-year-old Onesha, six-year-old Onya and four-year-old Olivia.

Police say the couple had an argument on Saturday. On Sunday morning, the family did not show up for church. Later in the afternoon, officers made a welfare check on the family. We're told everything looked normal, even though the officers did not go in the house. They knocked and didn't get an answer.

The wife's mother then went to the house at 10 p.m. Sunday, climbed in a window and found the bodies, police say.

We're told Clarence Washington was a janitor in the Culpeper school district.

Virginia State Police are assisting in the investigation.
